Answer:
Step-by-step explanation:
x² + 10x + 25
a² +2ab + b² = (a + b)²
b² = 25
b = √25
b = 5
2ab = 2*x*5 = 10x
1) 190,000,000 people
2) 1.86 x 10^8
The answer is letter C, which is (2,1)
IF they want to know the area you multiply all of them
So
16 x 20 x 8
You will get 2560
-14-(-6)= 8
There goes ur answer!!
